As bestshownin Fig. II; said flanges 11 i re wider at the end engaging saidrock shatt 4- than at the opposite end toward which they taper, and haverespectively semicircular rccesses 1% fitted to the cylindrical surfaceoi? said rock shaft. &. .Said web 12 is punched with two holes insymmetrical relation to said, recesses 14 to receive the U-bolt 16 whichhas the semicircular bight 17 complementary to said recesses 14 to forma bearing for said rock shaft; said bolt. 16 having nuts 18 to draw andhold it in the position shown in Fig. 111, encircling said shaft 4.between said flanges 11 of the lever 8 so as to rigidly clamp the latterupon said shaft in any desired angular relation with said shaft. It maybe observed, with reference to Fig. III, that the stress upon said bolt16 comes between, the flanges 11 of said lever 8, so as to engage saidrock shaft 4: at three Zones in axially spaced relation and thusstabilize and continually maintain said lever in rigid relation withsaid shaft l, whereas, a cast iron lever provided with a cylindricalhole and a. set screw, as above contemplated, has no such stabilizingcapacity.

Each of said levers 8 has at its end remote from said shaft 4, and inunitary relation with said flanges 11, a pair of lugs 19, and a rivet 20connecting said lugs through the upper end. of said link 9, in pivotalconnection therewith. Each of said brackets 10 has twoholes 21, forbolts'or rivets 2-2 rigidly connecting it with the lower rail 24. 01 itssash. 3' and, as indicated in Fig. II, each of said brackets 10 has apair of parallel lugs 25, embracing the lower end of the respectivelinkv 9,- and carrying a bolt 26 extending through said link and securedby a nut 27 thus forming a pivotal connection between said link andsash. Such construction permits the sashes to be disengaged from thelinks 9 without removing said brackets 10.

I do not desire to limit myself to the pre cise details of constructionand arrangement herein set forth, as it is obvious that variousmodifications may be made therein without departing from the essentialfeatures of my invention, as defined in the appended claims.

I claim:

1. Operating mechanism for a pivoted sash including a rock sha't'textending parallel with the axis of the sash pivots and carrying a leverconnected to the sash by a link; wherein said lever is a pressed sheetmetal channel bar having parallel flanges connected by a web in unitaryrelation therewith; each of said flanges having a recess fitted to saidrock shaft; a U-bolt encircling said rock shaft between said leverflanges,

and having its ends extending through said web; and nuts on said U-boltclumping waid bolt and lever in rigid relation with said shaft.

2. A sash operating mechanism including a lever, a link pivotallyconnected to said lever, and a bracket pivotally connected to theopposite end of said link; wherein said lever is Formed oi? pressedsheet metal. of U- shaped cross section, having a pair oi? flanges eachwith a substantially semicircular reces to lit a rock shaft: and aU-bolt carried by said lever having a bight cxtmiding between saidflanges complementary to said recesses to form a. bearing for said rockshalt.

A. sash operating mechanism including a lever and a link pivotallyconnected there with; wherein said lever is formed of pressed sheetmetal, of U-shapcd cross section, having a pair of flanges each with :1substantially semicircular recess to lit a rock shaft; and a U-boltcarried by said lever having a bight extending between said flangescomplementary to said recesses lo form a bearing for said rock shaft.

4. An article ol' manufacture, part of a sash operating mechanism,consisting of a lever formed of pressed sheet metal of U shaped crosssection, having a pair of flanges with recesses to fit a cylindricalsha'lt cxtending at right angles to said lever; said flanges beingconnected by a web in unitary relation therewith, and said webperforated to receive a clamp bolt between said recesses.

5. A lever element for pivoted window sashes in. the form of a metallicbar having a channeled cross sectional configuration and provided at oneend with an integral lateral projection adapted to serve as a pivot lug.

6. A lever element for pivoted window sashes in the form of a metallicbar having a channeled cross sectional configuration and provided at oneend with a pair of integral lateral projections adapted to serve aspivot ears; said ears being spaced to receive a link between them and apivot connecting said lever with said link.

7. A lever element for pivoted window sashes in the form oi a metallicbar having a channeled cross sectional configuration, the

flanges of said bar being of diilerent depths. at different regions ofthe length thereo'li said flanges forming integral lateral projcc tionsserving as pivot cars at the narrow end thereof and integral lateralprojections serving as sen'ii-sha'l't journals at the wider end thereof.

8. A lever mounting for pivoted window sashes, comprising a rock shaftand a lever element rotatably adjustable on said rock shaft, in the formof a channel. bar. the flanges of said bar being of" diflerent depths atdiflerent regions of the length thereof. and provided at the narrow endwith integral late-"ii proiections adapted to serve ill) lllb

lll)

iaameo as pivot ears, in spaced relation, and pro vided at the Wider endwith integral lateral projections, in axially spaced relation, each ofthe latter projections having a substan tially semicircularrecesstherein, adapted to tit said shaft; and a tl-bolt, having its endsextending through said bar, intermediate of said flanges, and having itstight in coaxial relation with said recesses in said flanges in wherebysaid lever element may; lie engaged with said shaft at three zones inaxially spaced relation. i

In testimony whereof, I have hereunto signed my name at Philadelphia,Pennsyt *ania, this fifth day of November, 1920.
